ArrayList<Movie> listItems = new ArrayList<Movie>();
MovieAdapter adapter = new MovieAdapter(mContext, R.layout.list_movie, listItems);
movieList.setAdapter(adapter); |
(mon listItems est rempli dans le asynctask class)
Le probleme est que l'application crashe a
Code:

2
| MovieAdapter adapter = new MovieAdapter(mContext, R.layout.list_movie, listItems);
movieList.setAdapter(adapter); |
Je pense que j'ai mal fait quelque chose dans ma class Adapter mais je ne trouve pas quoi ?

Juste ici
Code:

Quelqu'un pourrait il me conseiller ?
J'ai lus plusieurs tuto et je vois vraiment pas ce qu'il ne va pas : /
